Need power for my type x 12

R GOFF New member Username: Russ636 Post Number: 1 Registered: Mar-07	Posted on Wednesday, March 21, 2007 - 12:14 GMT I recently purchased an Alpine type x 12 and an Alpine mrd1005 amp. I an very disappointed. I have 8s that hit harder. The stereo shop tells me I need more power. The amp is ran at two ohms and the certificate syas it is pushing 1176 watts. Why does it sound so weak. How much power do I need to push this sub? Its in a good box and was professionally installed. Any suggestions on the right amp to push this sub?

Sounds like you have your sub wired wrong. For you to get that amp down to 2ohm you need a dual 4ohm sub and this is how you would wire it. http://www.cardomain.com/shop/wooferwizard.pl?num_of_subs=1&impedance_of_subs=4o hm_dvc&x=137&y=15

The coil jumpers have it running at 2 ohm. It barely shakes my rearview. Should I be thinking about boxes instead? The box is a sealed .75 cubic ft box that is in the trunk of my G35. Will a larger box get me more bass? maybe ported? What amp will make this speaker pound? Alpine pdx1.1000? Fosgate power 2000bd1? I have a capacitor and dont want to alter my cars charging system.

You will love this sub if you build the right box for it. I had to try four boxes last year and finally got it right.
